我正在写一些数学笔记，我想突出显示目录中（以及常规文本中的）某些部分（类似的章节、小节......）。
我所说的“突出显示”的意思是，在章节标题旁边（或附近）放置一些符号，以便读者可以注意到（可能通过脚注）文本的这些部分无论如何都是特殊的。
谢谢！

\importantstuff这里有一种方法，如果使用了开关，则会在页码后面附加一个小符号。这将持续\unimportantstuff到应用为止。
\documentclass{book}
\usepackage{tocloft}
\usepackage{graphicx}% For scalebox
\usepackage[tikz]{bclogo} % For 'funny' logos
\newif\ifimportantstuff
\newlength\pnumcontentskip
\setlength{\pnumcontentskip}{1.5em}% control the distance after the page number
\DeclareRobustCommand{\importantstuffsymbol}{\hskip\pnumcontentskip\scalebox{0.4}{\bcattention}}
\newcommand{\afterpnumcontent}{\ifimportantstuff\importantstuffsymbol\else\phantom{\importantstuffsymbol}\fi}
\makeatletter
\g@addto@macro\cftchapafterpnum\afterpnumcontent

% Switch the usage on
\newcommand{\importantstuff}{%

% Switch the usage off

**更新——带有一些可配置的界面。
用于\RedeclareStructureCommands启用或\RedeclareStructureCommands*禁用该功能。
条目的默认状态为“不重要”，可以用 更改符号tocsymbol，并用 给出注释tocsymbolnote。
0.4使用\tocsymbol、\inlinesymbol和宏以外的任何其他值来缩放符号大小\emptytocsymbol。
